It's
certainly inconvenient if your password is hacked and your identity stolen.
But if the CIA's password is hacked, it may mean a death sentence for
its covert operatives.

Recently, there was a huge setback for the CIA when its spies in Iran
and Lebanon were caught because their password was cracked. What was that
password? PIZZA:

In Beirut, two Hezbollah double agents pretended to go to work
for the CIA. Hezbollah then learned of the restaurant where multiple
CIA officers were meeting with several agents, according to the four
current and former officials briefed on the case. The CIA used the codeword
"PIZZA" when discussing where to meet with the agents, according
to U.S. officials. Two former officials describe the location as a Beirut
Pizza Hut. A current US official denied that CIA officers met their
agents at Pizza Hut.

From there, Hezbollah's internal security arm identified at least
a dozen informants, and the identities of several CIA case officers.

As I read the article, it seems that they used the CODEword "pizza" to talk about meeting at a Pizza Hut, rather than using a PASSword "pizza" on any computer resources. Not brilliant, certainly, but a different level of stupidity.
